Ride comfort. M-Sport springs are generally regarded as giving a terrible ride, although I don't even notice it personally (but then I have been driving M-Sports and S-Lines for years now).
I guess what he is referring to more though, is that spending less on the wheels and bodykit (a la M-Sport kit), you have the money to spend on a better engine, or enhanced spec.

Most 5 Series here seem to be very low spec with smallest diesel but M Sport. Finding a big spec car is a pain.
Ah I understand. Thanks
